Keyboard walk and widget tests

The Keyboard tab is part of review mode. View a post or page you can edit, choose Accessibility in the admin bar, and switch to Keyboard. Nothing runs until you ask, because both checks move focus around the page. Check keyboard access moves focus through the page as the Tab key would, up to 300 stops, and draws a numbered badge on each one. A "Tab order" list gives the same stops in words, and a checkbox hides the numbers.

The walk looks for what keyboard users run into: an element that shows no change when focused, focus that lands on something with no size, clipped, off screen or transparent, focus covered by a sticky header or cookie bar, Tab order that jumps back up the page, focus that reloads the page, changes the address or opens a dialog, content that appears on focus and stays open when Escape is pressed, and a script that stops the Tab key. Findings are listed with the usual severity, message and How to fix, and the badges are colored by the worst finding on each stop.

Test menus and pop-ups operates up to 40 widgets as a keyboard user would. It toggles disclosures, menus and accordions and checks their expanded state, looks for submenus that open on hover only, opens dialogs (including the Navigation block's mobile menu and common page builder pop-ups) and checks that focus moves in, they have a name, they are modal and they close with Escape, and presses arrow keys in tabs. Press Escape or choose Stop to end either run early; what was found so far is kept.
